2000 Pontiac grand am keep getting trouble code 113 air intake sensor high temp

Code 113 means the signal from the intake air temp sensor is too high. Sometimes the sensor has failed, sometimes there is a short in the wiring harness.

o2 sensor sense the amount of oxygen in exhaust stream.Let see 0Volt to 1volt= oVolt to 1000mv then 500mv is the middle .Over 500mv system is rich and under 500mv system poor. If ecm sense o2 sensor to be rich it will cut amount of fuel MAF sensor signal tell ECM air temp,and amount of air going inside intake manifold

Code 113 means the signal from the intake air temp sensor is higher than normal. The sensor is telling the computer the intake air is above 200 degrees. Could be a faulty sensor or wiring problem.

I don't show a code 113 for a Buick, but the code means the signal from the air temp sensor is high, which means the air temp is below zero or the sensor is faulty, or a problem with the wiring to the sensor.
Code 1676 is a problem with the canister purge solenoid which is how the computer vents the fuel tank. Could also be a problem with the vent for the tank.

Wow these are hard to find!!

If you have your owners manual they should be in there. I couldn't find one online but did find this.

I hope these helped you

Inspect the IAT sensor and wiring. The sensor is located in the air induction tube near the air filter. I've seen these wires break at the connector.

intake air temperature circuit,high input.Could be MAF(mass air flow sensor) or MAP(manifold absolute pressure switch).look for a sensor in the air inlet tube,MAF $100+$40core charge MAP $50.Make sure you give your code to the auto parts store for their recommendation as to which part is correct for your code

the code 113 is intake air temp cicuit, high input.
the code 102 is mass air flow volume air flow circuit, low input.
the code 171 is system too lean (bank 1)
I sure hope this helps you out. Dont sound like anything too major though

this problem I find in alot of 3.4 ltre grand-ams and that is the wiring go to the intake air temp sensor is broken at the connector. the wire will look good but in the insulation it will be broken. just give each wire a tug, if the wire pulls out then that is the broken one.

the meaning of the code is > intake air temperature circuit high input , .
